I work in a very small office (3 people, most times just 2) and was told for the summer I can work from home on Fridays if I can get a VPN going. Awesome and exciting however I'm not the best networking person.

Work has a static IP and my work PC is running XP Pro - home PC has Win7 HP.

The problem is that I'm getting the 800 error at home - I'm able to log in just fine but it won't connect. I did some searching and it seems that error 800 can be just about anything. After reading an article I opened the following ports on my work PC: 47, 443, 500, 1701 and 1723.

I have never setup a VPN before but I 'believe' I set it up correctly (setting it up seems rather straight forward).
